Code Change Impact Report

Generated: 2025-11-05T10:38:08.083552 Agent: CodeChangeWatcher

Changes Summary

1. Loop Resilience Fix (CRITICAL)

  • File: core/orchestrator.py
  • Change: Move exception handling inside loop
  • Impact: Orchestrator now continues on cycle errors instead of exiting
  • Tests: test_run_loop_continues_on_cycle_error

2. Timeout Protection (HIGH)

  • File: core/orchestrator.py (lines 105-109)
  • Change: Add 30s timeout to strategy analysis
  • Impact: Prevents hangs from slow analysis
  • Tests:
    • test_run_once_analysis_timeout
    • test_run_loop_timeout_continues

3. Position Limit Cap (HIGH)

  • File: core/orchestrator.py (lines 129-131)
  • Change: Add MAX_SHARES_PER_ORDER = 10,000 cap
  • Impact: Safety limit on order size
  • Tests:
    • test_run_once_position_limit_cap
    • test_run_once_position_within_limit

Dependencies Affected

Direct Callers

  • core/api_server.py → start_trading()
  • cli/dashboard.py → WebSocket handlers
  • Test suite → 42 tests

External Calls

  • strategy_agent.analyze_stock() (now timeout-protected)
  • paper_trader._get_market_price()
  • risk_manager.check_portfolio_heat()
  • order_manager.place_market_order()

Test Coverage

New Tests (6 total)

  1. ✅ test_run_loop_continues_on_cycle_error - Validates loop fix
  2. ✅ test_run_loop_timeout_continues - Validates timeout handling
  3. ✅ test_run_once_analysis_timeout - Validates analysis timeout
  4. ✅ test_run_once_position_limit_cap - Validates position cap
  5. ✅ test_run_once_position_within_limit - Validates uncapped positions

Coverage Metrics

  • Orchestrator coverage: 98.84%
  • Total tests: 42
  • Test passing rate: 100%

Risk Assessment

Breaking Changes

  • ⚠️ Loop behavior changed (continues vs exits)
    • Mitigation: All existing tests pass, new tests validate

Side Effects

  • ✅ Timeout may cause occasional skip of slow analysis
    • Mitigation: Logged and tracked as timeout event
  • ✅ Position size capped at 10,000 shares
    • Mitigation: Safety feature, configurable constant

Recommendations

  1. Deploy to Staging - Monitor loop behavior in realistic scenario
  2. Monitor Timeouts - Track analysis timeout frequency
  3. Monitor Position Capping - Check if 10k cap is hit frequently
  4. Update Documentation - Document new limits and behavior
